Indicators of clean water (and other things)
The 2-3's brought their water testing equipment to the Parker creek today. During their Stream to River clean water project they have visited the Hudson three times to collect data. Now they will compare their data on turbidity, pH, flow, chlorophyll, plant and animal life and other indicators, to our own stream. One more trip to the Hudson is planned for May. Of course our creek is available any day for testing.
Their usual partners, the 6-7's, were at the Clark Museum in Williamstown today, so 2-3's handled things on their own. They have lots of field experience, so the kids got right to work.
One of their informal tests is to see who can go deepest in the water without flooding their boots - wet socks (and screaming) are the indicators!
